Presidio roofing work in Presidio, San Francisco County — inspection, repair, replacement and coatings, quoted in writing and permitted where the work requires it.

1Roof Age Across Presidio

Streets in Presidio that were built out together tend to call for roofs together, which is why one re-roof often brings three more on the same block. That is as true in Presidio as anywhere in San Francisco County. Garage and patio roofs in Presidio are frequently lower slope than the house and require an entirely different system. Original decking on older Presidio homes is often skip sheathing, which changes what can be laid over it. Older Presidio buildings frequently sit on their second or third covering, and the layer count matters more than the age when planning the next one. The majority of roof coverings in Presidio fall into three groups: original coverings near the end of their life, replacements from the last two decades, and low-slope sections added later.

Put simply, vents and caps corrode faster than the roof in Presidio, and replacing them during a re-roof costs almost nothing. Fasteners are the weak point within a mile of the water in Presidio; plated nails give out while the covering above them still has years left. Any exposed metal on a Presidio roof wants a coating or a sacrificial finish, not bare galvanised left to weather.

2Preventative Work on Presidio Roofs

Annual inspection on a Presidio property typically adds two to three years to the back end of a roof's service life. A Presidio roof with working drainage outlasts an identical roof without it by years. Clearing the Presidio gutters in late autumn prevents most of the harm the soonest storm would otherwise cause. A maintenance record on a Presidio roof also helps at claim time, because it shows the failure was sudden rather than neglected. Keeping a dated maintenance file on a Presidio property pays for itself the soonest time a claim is questioned. Put simply, checking the attic after the first heavy wet weather in Presidio finds leaks while they are still stains rather than damage. It is the same story on most Presidio streets.

In practice, permit fees in Presidio are a small part of the job and a large part of what protects the owner at resale. In practice, structural work on a Presidio roof triggers a separate review beyond the roofing permit itself. Solar removal and reset on a Presidio work can need its own electrical permit alongside the roofing one.

3Pricing a Presidio Roof Honestly

Patch makes sense on a Presidio roof with life left and a localised failure, and nowhere else. Seasonal demand in Presidio affects scheduling more than price, but booking ahead of the rains helps both. Material choice changes a Presidio roof covering budget less than most owners expect; labour and complexity dominate. Cheap Presidio quotes usually skip the flashing. That is where the money is saved and where the next leak arrives. Square footage is only half the cost of a Presidio roof covering; pitch, access and layer count move the number as much. That is as true in Presidio as anywhere in San Francisco County.

Ask a Presidio contractor for recent addresses nearby and go and look at the work from the street. A Presidio roofer who will not put the assembly in writing is not quoting the same project as the one who will. Realistically, a contractor who explains why a Presidio roof covering failed is more use than one who only quotes to swap out it.

4Presidio Roofing and Your Policy

Realistically, we do not advise filing a Presidio claim where the deterioration is clearly age, given that a declined claim stays on the record. That is as true in Presidio as anywhere in San Francisco County. Partial claims on a Presidio roof are common and should be priced as repairs rather than inflated into replacements. Realistically, actual cash value and replacement cost behave very differently on an older Presidio roof covering, and the policy wording decides which applies. It is the same story on most Presidio streets. Deductibles on Presidio policies vary enough that the claim decision changes case by case. In practice, emergency tarping on a Presidio roof covering is normally covered, and receipts should be kept for it.

Moisture readings matter on Presidio low-slope roofs. Coating over wet insulation seals the problem in rather than solving it. Put simply, a Presidio roof is inspected from the attic as well as the roof surface; half the evidence is underneath. Granule loss in the gutters is the earliest honest signal on a Presidio shingle roof, and it shows up years in advance of a ceiling stain does. San Francisco County is no different.

5Which System Fits a Presidio Property

Architectural shingle outperforms three-tab on a Presidio roof for a modest extra cost and a meaningfully longer life. Realistically, concrete tile suits Presidio buildings designed for the weight; laying it on framing that was not is a structural question first. Worth knowing before you sign anything. Synthetic composite has become a credible option in Presidio where the look of slate or shake is wanted without the weight or the fire risk. We see it on Presidio roofs every week. Composition shingle is the most common covering in Presidio and the cheapest to replace, but it is also the soonest to show UV damage. Realistically, lightweight tile gives Presidio owners the look without the structural upgrade older framing would otherwise need.

Supplements are normal on Presidio claims once the covering is off and the deck is visible, and they should be raised with evidence rather than argued later. That is as true in Presidio as anywhere in San Francisco County. As a rule, a Presidio adjuster works from the scope in front of them, which is why the contractor's report has to be thorough. We the project alongside the adjuster on Presidio claims rather than around them, which keeps the scope honest and the timeline shorter.

6What to Ask a Presidio Roofer

In practice, ask any Presidio roofer what happens if the deck is worse than expected, and get the answer ahead of the covering comes off. We see it on Presidio roofs every week. Payment schedules on Presidio the project should track progress, never run ahead of it. As a rule, check that the Presidio crew doing the work is employed by the company quoting it. This holds across San Francisco County. Ask a Presidio contractor for recent addresses nearby and go and look at the the project from the street. The Presidio roofing company who tells you a patch will do, when a repair will do, is the one worth calling back. Local experience matters in Presidio because the failure modes here are heat, gusting and drainage rather than snow and ice.

A Presidio roof covering is inspected from the attic as well as the roof covering surface; half the evidence is underneath. Infrared scanning on a Presidio commercial roof locates wet insulation that no visual inspection would find. Core samples settle the argument on a Presidio low-slope roof when moisture is suspected but not visible.

7Presidio Permit Requirements

Put simply, unpermitted roofing in Presidio surfaces at resale. the San Francisco Department of Building Inspection keeps the record, and a buyer's inspector knows to look for it. Historic districts near Presidio may restrict covering type and colour, which is worth confirming before materials are ordered. Fire-zone properties around Presidio carry assembly requirements that the permit will check against. We see it on Presidio roofs every week. In practice, the job in Presidio is inspected as well as permitted — the San Francisco Department of Building Inspection signs off the finished assembly, not just the application. Put simply, permit requirements in Presidio run through the San Francisco Department of Building Inspection. Minor repairs usually do not need one; a tear-off and replacement does.

Phasing a large Presidio building across two seasons is commonly cheaper than financing the whole project at once. We see it on Presidio roofs every week. Put simply, written, itemised estimates let Presidio homeowners compare bids properly rather than guessing at what is included. As a rule, repair makes sense on a Presidio roof covering with life left and a localised failure, and nowhere else. San Francisco County is no different.

8How We Inspect a Presidio Roof

On most jobs, a Presidio roof covering is inspected from the attic as well as the roof surface; half the evidence is underneath. Realistically, moisture readings matter on Presidio low-slope roofs. Coating over wet insulation seals the problem in rather than solving it. Flashing at the wall junction is checked first on any Presidio inspection, because that is where most ceiling stains originate. Lifting a few tiles in two or three places is the only way to date the underlayment on a Presidio tile roof, and it takes fifteen minutes. Infrared scanning on a Presidio commercial roof locates wet insulation that no visual inspection would find. It is the same story on most Presidio streets.

As a rule, two warranties apply on Presidio work: the manufacturer's on the material and the installer's on the workmanship. Ask for both. We see it on Presidio roofs every week. Local references beat national brand badges on any Presidio roofing decision. A Presidio roofer who will not put the assembly in writing is not quoting the same project as the one who will.

9Presidio Roofing and the Local Climate

As a rule, shaded north slopes in Presidio hold moisture well past sunrise, which is why moss shows up there first and nowhere else. That is as true in Presidio as anywhere in San Francisco County. Fog drip in Presidio delivers more moisture than the rain gauge suggests, and it arrives nightly rather than in storms. Put simply, marine layer keeps Presidio roofs damp into late morning most of the year, and slow-drying surfaces favour moss on the shaded slopes. Gutters on Presidio properties corrode from the inside, and the first sign is as a rule staining on the fascia rather than a visible hole. That is as true in Presidio as anywhere in San Francisco County. Any exposed metal on a Presidio roof covering wants a coating or a sacrificial finish, not bare galvanised left to weather. As a rule, timber in Presidio roofs carries more moisture year-round, so deck condition counts more here than the age of the covering.

Matching provisions in a policy matter on Presidio tile roofs where the original profile is discontinued. As a rule, actual cash value and replacement cost behave very differently on an older Presidio roof, and the policy wording decides which applies. We work alongside the adjuster on Presidio claims rather than around them, which keeps the scope honest and the timeline shorter.

Presidio roofing work in Presidio, San Francisco County — inspection, repair, replacement and coatings, quoted in writing and permitted where the work requires it.

1Presidio Roofing and the Local Climate

Shaded north slopes in Presidio hold damp well past sunrise, which is why moss shows up there first and nowhere else. Vents and caps corrode faster than the roof covering in Presidio, and replacing them during a re-roof costs almost nothing. Put simply, gutters on Presidio properties corrode from the inside, and the first sign is usually staining on the fascia rather than a visible hole. Worth knowing before you sign anything. Fog drip in Presidio delivers more moisture than the rain gauge suggests, and it arrives nightly rather than in storms. Realistically, ponding on a Presidio low-slope roof dries slowly in marine air, which gives the membrane a harder life than the wet weather total suggests. It is the same story on most Presidio streets.

Reclaimed tile can be matched on Presidio heritage roofs, but the underlayment beneath it should always be new. Mixing materials across a Presidio roof is fine provided each section gets the system it needs and the transitions are flashed properly. As a rule, composition shingle is the most common covering in Presidio and the cheapest to swap out, but it is also the earliest to show UV damage. San Francisco County is no different.

2Presidio Permit Requirements

As a rule, full replacements in Presidio generally require a permit through the San Francisco Department of Building Inspection, with an inspection once the work is finished. Fire-zone properties around Presidio carry assembly requirements that the permit will look over against. Reroofing over existing layers in Presidio is limited by code, and the layer count is checked at inspection. Commercial work in Presidio usually involves more review than residential and a longer lead time. Realistically, permit requirements in Presidio run through the San Francisco Department of Building Inspection. Minor repairs usually do not need one; a tear-off and replacement does. A permitted Presidio re-roof leaves a record that supports any later insurance claim on the same roof covering. That is as true in Presidio as anywhere in San Francisco County.

In practice, clearing the Presidio gutters in late autumn prevents the majority of of the damage the first storm would otherwise cause. Moss on a shaded Presidio slope should be treated rather than scraped, since scraping takes the granules with it. In practice, keeping a dated maintenance file on a Presidio property pays for itself the first time a claim is questioned.

3Maintaining a Presidio Roof

Keeping a dated maintenance file on a Presidio property pays for itself the first time a claim is questioned. We see it on Presidio roofs every week. Loose ridge caps on a Presidio roof are a five-minute fix in advance of the winds and a much larger one after. Realistically, clearing the Presidio gutters in late autumn prevents most of the damage the first storm would otherwise cause. We see it on Presidio roofs every week. Resealing penetrations on a Presidio roof every few seasons is the cheapest work anyone will ever do on the building. Two visits a year keeps a Presidio roof honest: clear the valleys and gutters ahead of the rains, and look over the flashings after the first heavy storm. Realistically, most Presidio roofs that give out early fail at a penetration someone could have resealed for a few hundred dollars.

Many Presidio properties carry a covering chosen for price rather than climate, and it shows in how early it gives out. This holds across San Francisco County. On most jobs, multi-unit buildings in Presidio usually need a low-slope system and a maintenance plan rather than a one-off repair. This holds across San Francisco County. Additions and conversions are common in Presidio, and the joint between the original roof and the newer section is where most leaks begin. This holds across San Francisco County.

4Presidio Roofing and Your Policy

Photographs taken before any tarping on a Presidio property are the most valuable evidence in the whole claim. It is the same story on most Presidio streets. Policies covering Presidio properties generally pay for sudden damage and not for age, so the report has to separate the two clearly. This holds across San Francisco County. Most Presidio claims that let go do so because the damage was cleaned up or patched in advance of anyone photographed it. Denied Presidio claims are often reopened successfully when correct documentation is supplied the second time. Matching provisions in a policy matter on Presidio tile roofs where the original profile is discontinued. Actual cash value and replacement cost behave very differently on an older Presidio roof covering, and the policy wording decides which applies.

Two visits a year keeps a Presidio roof honest: clear the valleys and gutters before the rains, and check the flashings following the soonest heavy storm. Skylight seals on Presidio roofs want checking annually, as they fail quietly and drip into the ceiling cavity. San Francisco County is no different. Realistically, the majority of Presidio roofs that fail early give out at a penetration someone could have resealed for a few hundred dollars.

5Roofing Materials That Suit Presidio

On most jobs, reclaimed tile can be matched on Presidio heritage roofs, but the underlayment beneath it should always be new. Put simply, lightweight tile gives Presidio owners the look without the structural upgrade older framing would otherwise call for. As a rule, flat and low-slope sections in Presidio need a membrane or a coating system, not shingle laid at a pitch it was never designed for. It is the same story on most Presidio streets. Architectural shingle outperforms three-tab on a Presidio roof for a modest extra cost and a meaningfully longer working life. This holds across San Francisco County. Underlayment choice counts more than covering choice on a Presidio tile roof covering, because that is the layer doing the waterproofing. That is as true in Presidio as anywhere in San Francisco County.

As a rule, nearly all roofs in Presidio fall into three groups: original coverings near the end of their life, replacements from the last two decades, and low-slope sections added later. Solar arrays on Presidio roof coverings complicate replacement, and the panel age rarely matches the roof age. On most jobs, a Presidio property often carries more than one roof covering type — a pitched main house in one material and a flatter garage or addition in another. Worth knowing before you sign anything.

6Pricing a Presidio Roof Honestly

On most jobs, a Presidio quote that comes in far below the others is as a rule missing the flashing, the permit or the disposal. This holds across San Francisco County. A Presidio estimate worth reading itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up separately. Budgeting a Presidio replacement a few years out costs nothing and removes the pressure of choosing a roofing company during a storm. San Francisco County is no different. Repair makes sense on a Presidio roof with service life left and a localised failure, and nowhere else. We see it on Presidio roofs every week. Cost on a Presidio roof covering comes down to size, pitch, how many layers come off, and what the deck looks like underneath.

As a rule, valley condition is the single best indicator of how a Presidio roof has been maintained. Core samples settle the argument on a Presidio low-slope roof covering when water is suspected but not visible. Flashing at the wall junction is checked first on any Presidio inspection, given that that is where the majority of ceiling stains originate.

7The Presidio Inspection, Step by Step

A proper Presidio inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb fail long before the covering does. Core samples settle the argument on a Presidio low-slope roof when moisture is suspected but not visible. Realistically, we check ventilation on every Presidio job, because a roof that cannot breathe will not reach its rated life. On most jobs, flashing at the wall junction is checked earliest on any Presidio inspection, since that is where nearly all ceiling stains originate. As a rule, valley condition is the single best indicator of how a Presidio roof covering has been maintained. This holds across San Francisco County. Lifting a few tiles in two or three places is the only way to date the underlayment on a Presidio tile roof, and it takes fifteen minutes. San Francisco County is no different.

Manufacturer certification matters on Presidio jobs because it is what makes the material warranty enforceable. Two warranties apply on Presidio work: the manufacturer's on the material and the installer's on the workmanship. Ask for both. It is the same story on most Presidio streets. On most jobs, clean-up and magnetic nail sweep should be in the Presidio contract, not assumed.

8Vetting a Contractor in Presidio

Clean-up and magnetic nail sweep should be in the Presidio contract, not assumed. Put simply, the Presidio contractor who tells you a repair will do, when a make good will do, is the one worth calling back. Manufacturer certification matters on Presidio jobs given that it is what makes the material warranty enforceable. This holds across San Francisco County. Realistically, documented scope, itemised price and a written warranty are the minimum on any Presidio work. Ask any Presidio roofer what happens if the deck is worse than expected, and get the answer ahead of the covering comes off.

In practice, infrared scanning on a Presidio commercial roof locates wet insulation that no visual inspection would find. San Francisco County is no different. Put simply, flashing at the wall junction is checked soonest on any Presidio inspection, given that that is where most ceiling stains originate. Put simply, valley condition is the single best indicator of how a Presidio roof covering has been maintained.

9What Sits on Most Presidio Roofs

Converted garages in Presidio are a common source of leaks because the roof was never upgraded with the conversion. Streets in Presidio that were built out together tend to call for roofs together, which is why one re-roof often brings three more on the same block. Realistically, garage and patio roofs in Presidio are frequently lower slope than the house and need an entirely different system. Many Presidio properties carry a covering chosen for price rather than climate, and it shows in how early it gives out. Housing stock in Presidio runs across several eras, and each one brings its own roof. What sits above the ceiling generally tells you when the building went up. Nearly all roofs in Presidio fall into three groups: original coverings near the end of their working life, replacements from the last two decades, and low-slope sections added later.

A Presidio inspection should end with a written report and photographs, not a verbal summary and a price. Lifting a few tiles in two or three places is the only way to date the underlayment on a Presidio tile roof, and it takes fifteen minutes. Infrared scanning on a Presidio commercial roof covering locates wet insulation that no visual inspection would find.

Presidio roofing work in Presidio, San Francisco County — inspection, repair, replacement and coatings, quoted in writing and permitted where the work requires it.

1Material Options for Presidio Roofs

Metal has grown in Presidio for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. Standing seam on a Presidio property hides its fixings, which removes the most common leak path on exposed metal. It is the same story on most Presidio streets. Realistically, tPO and modified bitumen both work on Presidio low-slope roofs, and the choice usually comes down to detailing rather than the sheet. On most jobs, tile is widespread across Presidio, and the tile will outlive the underlayment beneath it by decades — which is what catches owners out. Worth knowing before you sign anything. Put simply, silicone coatings hold up well on Presidio roofs that pond slightly, where acrylic would not. Lightweight tile gives Presidio owners the look without the structural upgrade older framing would otherwise need.

On most jobs, ask any Presidio roofer what happens if the deck is worse than expected, and get the answer in advance of the covering comes off. Manufacturer certification counts on Presidio jobs since it is what makes the material warranty enforceable. Beware the Presidio estimate that expires today; urgency is a sales tactic, not a roofing condition. That is as true in Presidio as anywhere in San Francisco County.

2The Conditions a Presidio Roof Works Against

Fasteners are the weak point within a mile of the water in Presidio; plated nails give out while the covering above them still has seasons left. As a rule, skylight curbs on Presidio roof coverings fail early; the seal takes salt, UV and movement at the same time. This holds across San Francisco County. Salt air is the quiet problem on a Presidio roof. It attacks fasteners, flashing and any exposed metal long before the covering itself looks tired. Gutters on Presidio properties corrode from the inside, and the first sign is generally staining on the fascia rather than a visible hole. Put simply, roofs near the water in Presidio corrode from the fixings outward. The shingle can look sound while the nails holding it have lost half their section. Timber in Presidio roofs carries more moisture year-round, so deck condition matters more here than the age of the covering. It is the same story on most Presidio streets.

The permit record for a Presidio property is public, which is how a buyer's inspector checks the roof was done properly. On most jobs, a permitted Presidio re-roof leaves a record that supports any later insurance claim on the same roof. Realistically, reroofing over existing layers in Presidio is limited by code, and the layer count is checked at inspection.

3What Roofing Costs in Presidio

Put simply, repair makes sense on a Presidio roof covering with working life left and a localised failure, and nowhere else. Budgeting a Presidio replacement a few years out costs nothing and removes the pressure of choosing a roofer during a storm. Cost on a Presidio roof comes down to size, pitch, how many layers come off, and what the deck looks like underneath. In practice, a Presidio estimate worth reading itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up separately. In practice, deck replacement on a Presidio work is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. San Francisco County is no different. A Presidio roof covering quoted without anyone looking in the attic is a quote based on half the information.

In practice, resealing penetrations on a Presidio roof every few years is the cheapest the job anyone will ever do on the building. Clearing the Presidio gutters in late autumn prevents most of the damage the first storm would otherwise cause. This holds across San Francisco County. Most Presidio roof coverings that fail early give out at a penetration someone could have resealed for a few hundred dollars. San Francisco County is no different.

4Hiring Well in Presidio

A good Presidio roofer will talk you out of work you do not require, which is the clearest signal there is. Local experience is what decides it in Presidio given that the failure modes here are high temperatures, wind and drainage rather than snow and ice. Ask a Presidio roofer for recent addresses nearby and go and look at the the job from the street. As a rule, written scope, written price and a written warranty are the minimum on any Presidio job. We see it on Presidio roofs every week. Local references beat national brand badges on any Presidio roofing decision.

In practice, standing seam on a Presidio property hides its fixings, which removes the most common leak path on exposed metal. Metal has grown in Presidio for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. Cool-rated coverings are worth specifying in Presidio even where code does not require them.

5Presidio Roofing and Your Policy

We do not advise filing a Presidio claim where the damage is clearly age, since a declined claim stays on the record. San Francisco County is no different. Emergency tarping on a Presidio roof covering is normally covered, and receipts should be kept for it. Put simply, code upgrade cover decides whether a Presidio claim pays for bringing the assembly current or only for like-for-like. Photographs taken before any tarping on a Presidio property are the nearly all valuable evidence in the whole claim. San Francisco County is no different. Matching provisions in a policy matter on Presidio tile roofs where the original profile is discontinued.

On most jobs, we check ventilation on every Presidio job, given that a roof that cannot breathe will not reach its rated service life. Granule loss in the gutters is the earliest honest signal on a Presidio shingle roof, and it shows up seasons before a ceiling stain does. This holds across San Francisco County. Drone access on steep or fragile Presidio roofs gets the detail without anyone walking a covering that cannot take it.

6What a Presidio Inspection Covers

We inspect the deck from inside the attic on every Presidio work. Daylight through the sheathing tells you more than anything visible from the driveway. Damp readings matter on Presidio low-slope roofs. Coating over wet insulation seals the trouble in rather than solving it. Flashing at the wall junction is checked soonest on any Presidio inspection, given that that is where most ceiling stains originate. Put simply, we photograph every elevation on a Presidio work so the written estimate can be read against what is actually up there. We check ventilation on every Presidio job, because a roof that cannot breathe will not reach its rated service life.

Marine layer keeps Presidio roofs damp into late morning most of the year, and slow-drying surfaces favour moss on the shaded slopes. In practice, onshore wind carries salt several blocks inland here, so Presidio roof coverings call for galvanised or stainless fixings rather than the cheaper plated stock. This holds across San Francisco County. Put simply, gutters on Presidio properties corrode from the inside, and the first sign is in most cases staining on the fascia rather than a visible hole.

7Housing Stock and Roof Types in Presidio

In practice, most roof coverings in Presidio fall into three groups: original coverings near the end of their service life, replacements from the last two decades, and low-slope sections added later. As a rule, additions and conversions are common in Presidio, and the joint between the original roof and the newer section is where most leaks begin. Second-storey additions in Presidio create a junction between old and new roof that needs proper flashing rather than sealant. Converted garages in Presidio are a common source of leaks given that the roof was never upgraded with the conversion. As a rule, original decking on older Presidio homes is frequently skip sheathing, which changes what can be laid over it. Where Presidio buildings have been re-roofed twice, the next job is a tear-off regardless of what the property owner would prefer. We see it on Presidio roofs every week.

Infrared scanning on a Presidio commercial roof locates wet insulation that no visual inspection would find. We check ventilation on every Presidio project, since a roof that cannot breathe will not reach its rated life. Photographs with dates are part of every Presidio inspection, because an undocumented claim gets read as wear and tear by any adjuster.

8The Presidio Maintenance Year

Clearing the Presidio gutters in late autumn prevents nearly all of the harm the first storm would otherwise cause. On most jobs, drainage is the cheapest maintenance on any Presidio building — blocked outlets cause more harm here than the storms themselves. Realistically, skylight seals on Presidio roofs want checking annually, as they fail quietly and drip into the ceiling cavity. Keeping a dated maintenance file on a Presidio property pays for itself the first time a claim is questioned. Trimming back branches over a Presidio roof removes the debris that holds moisture against the covering and shortens its life. It is the same story on most Presidio streets. On most jobs, a maintenance record on a Presidio roof covering also helps at claim time, since it shows the failure was sudden rather than neglected.

Deductibles on Presidio policies vary enough that the claim decision changes case by case. Supplements are normal on Presidio claims once the covering is off and the deck is visible, and they should be raised with evidence rather than argued later. San Francisco County is no different. Wind and storm harm on a Presidio roof covering is covered where it is documented; wear is not covered anywhere. That is as true in Presidio as anywhere in San Francisco County.

9Presidio Permit Requirements

Full replacements in Presidio generally require a permit through the San Francisco Department of Building Inspection, with an inspection once the work is finished. That is as true in Presidio as anywhere in San Francisco County. On most jobs, permit requirements in Presidio run through the San Francisco Department of Building Inspection. Minor repairs usually do not need one; a tear-off and replacement does. That is as true in Presidio as anywhere in San Francisco County. Realistically, the San Francisco Department of Building Inspection handles the paperwork for roofing work in Presidio, and a licensed contractor pulls it as part of the job rather than leaving it to the owner. Permit fees in Presidio are a small part of the work and a large part of what protects the property owner at resale. Work in Presidio is inspected as well as permitted — the San Francisco Department of Building Inspection signs off the finished assembly, not just the application.

Where Presidio buildings have been re-roofed twice, the next project is a tear-off regardless of what the homeowner would prefer. We see it on Presidio roofs every week. Converted garages in Presidio are a common source of leaks since the roof was never upgraded with the conversion. Multi-unit buildings in Presidio usually need a low-slope system and a maintenance plan rather than a one-off repair. This holds across San Francisco County.
